To all whom it may concern:

Be it known that I,EDGAR M. MATTHEWS,

I a citizen of the United States, residing at Chicago, inthe county ofCook and State of Illinois, have .invented a new anduseful Improvementin WindoweSash, of which the following is a specification. The primaryobject of `myinvention is to provide a construction of window-sashwhereby the pane of glass which' it is designed to hold may be readilyintroduced into and secured in it, and a broken pane may fbe. removedlfrom it, without requiring the sash to Ebe removed from the window.

While my invention may be used in win dow-sash generally, I Vhavedevised it more especially for sheet-metal sash'and particularl)7 foruse inthe windows-oi railway cars, whichis fthe form thereof illustratedin the accompanyin drawings, in which- Figure 1 s ows my improved sashby a view .in rontjelevation; Fig. 2 is an :enlarged section 4on'theirregular line 2 2, Fig. 7

Fig. 3 is labrolren plan view of the.y sheetmetal blank lirom which the'sash-trarne is formed; Fig. 4 l:is an enlarged broken perspective view-ofa section of one-of *the sash-A rails formed lout 'of the blank; Fig.5 lis a.

t-The blank l2 (Fig. 3) is a continuous 'sheet-'metal 'strip ofgenerally-rectangular -cr'oss section with coincident V shaped notches,one pairof which is Vshown at 13 in its opposite edges, 'and the endsbeing simila-rly beveled. These notches ldene the blank-sections, all ofwhich are alike for an equilateralk rectangular sashV such as that shown-in Fig. 1, but may otherwise vary in length. To vform the fourrails ofa sash 14 the Vblank'sections are bent at their junctions between -the'notches to extend at rightv 'angles -to 'each other and, preliminarythere. 'to, are each 'bent along the brokenr lines veach lrecess isshown on the blank. Thus-the relativelyT wider and narrower sidesl `and17 are bent along the lines 151 and 171 to extend parallel with eachother and form of'the part 19 between the bending-lines the marginalface 20 (Fig. 7) or base of the rail. Each side 15, which forms theouter face `21 of the respective rail, is then curved along .the line.

152 to form the crown 22 and the part 16 of the blank-section is bentinwardly to extend parallel withv the face 21 and form the inner wall 23of the crown, and again-at rightangles to the wall 23 to form a seat 24-for the window-pane 2 5 in its trough-like cushion 26 of softrubber orother suitable material for cushioning the glass against fracture fromshock, jar and .the like.

The'bendin of the.blanksections firstdescribed as O rming of each theface 20,

4`produces of the part 17 the innerface 27 of the respective sash-rail,which is Jbent along the line 172 on the blank to extend-"at aright-angle to the face 27 `and form the shoulder 28, leaving the part18 of each blank-section to form, by bending along the line 181th'eoifset wall 29, which 'is united along its edge, -as by brazing orwelding, to the opposing edge of 'the seat 24,.the line of junctionbeing indicated at -30 in Fig. 4;

and the -intertting-cornerforming beveled ends ci the rails should beunited in `the same vway to complete the sash-frame. (In the edge of thewider part 15 of-each blank-` `section near its ends are formed similarrecesses y31, and in direct alinement with each blank-'section acircular opening 32;

, andeircula-r open-ings 33 are formed inthe parts 15 of theblank-sections, Ain alinement with thev recesses 31, vto Aprovidepin-holes (Fig. 7) for the purpose hereinafter eX- plained.I

Prior to uniting the edges of the railsalong the line 30 aclamping-block 311 (Figs.

A8 and 9) is introducedvinto place, one in eachend of each rail. Thisblock comprises a stem 35 providedon-one end with a' curved head 36conforming 'to and litting within the crown 22, the stem containing alongitudinal bore 37 'of rectangular cross-section terminating at itsouter end in a socket 3S havin an .inclined inner wal to exert the'cain-v notion hereinafter described. In placing the blocks 34: in therespective rails,

`each is caused to register apin-socket 39 provided in the part 17 ofico` ' -head36 with a hole 33fto permit a pin 40 -to be .driven throughthe hole into the socketl y plying a bead to the sash, a key 45`is in-.k that head, with a narrow cylindrical section 451 of a diameteradapting a bead-slot 44 to the 'rectangular bore through lthe stem 35 lof the'clamping-head 3 4; and the keystern f manner to'cause its slots44 tostraddle. the
